Preliminary sizing methodologies for regional aircraft with liquid hydrogen fuel and SOFC-GT-Battery hybrid-electric powertrains

Solid Oxide Fuel Cell (SOFC) systems for aviation applications have been considered for their use as APUs or powertrains, as standalone systems or in combination with gas turbines, and both fueled by reformed Jet-A or by hydrogen. Most existing studies focus on powertrain performance modelling. In this work, traditional tube-and-wing regional...

Thermodynamic Modeling of High Temperature Heat Pump Systems

Industrial processes are estimated to be responsible for about 20 % of the total greenhouse gas emissions within the European Union (EU). The majority of the industrial energy demand is related to the thermal energy required for process heating. Thus, there is a need to make radical changes to the industrial heating supply to achieve net-zero...

Weight Estimation of Gas Turbine Engines: Development of a Component-Based Preliminary Engine Design Tool

The need for more efficient aircraft has spawned the conception of a variety of novel engine and aircraft architectures, such as the combined-cycle engine proposed by researchers at Delft University of Technology. To evaluate the potential benefits of these concepts comprehensively, in-depth performance simulations are required. Furthermore,...

Preliminary Design of a Recuperator for a Gas Turbine Range Extender Application

Range extended electric vehicles (REEV) are being considered as a possible solution for the electrification of passenger vehicles. The application of a recuperated gas turbine (GT) for REEVs shows potential in terms of power-to-weight ratio, emissions and cost. The recuperator plays a major role in achieving target efficiency, while being a main...

Analyses and dynamic modelling of the compressor section in a PCC-process for coal-fired power plants with offshore storage

Carbon dioxide (CO2) is one of the main greenhouse gases that contributes to the current climate change. Its increasing share in the Earth atmosphere leads to an increase in global temperature. To prevent the sea level from rising and increased severity of extreme weather, many governments are now trying to reduce their carbon footprint. One...
